According to the evidence in the Collin County case, Warterfield
broke into a home on Dec. 9, 1989, took a sleeping 9-year-old girl from
her bed, and carried her outside with a pillowcase over her head.
Warterfield sexually assaulted the girl in a grassy area and then
disappeared.

After the attack, the girl spat into the grass and onto the
pillowcase. Police recovered the pillowcase, which showed the presence
of semen. Full DNA testing was done in 2010. Results showed the stain on
the pillowcase to be a mixture of DNA belonging to the girl and
Warterfield.

Earlier this year a Dallas County jury gave Warterfield a life sentence in a similar case involving
an attack on a 7-year-old girl. Under a 1989 law, he would have been
eligible for parole after 15 years. Because the conviction in Collin
County was stacked, Warterfield must serve all of his Dallas County
sentence before he can start accruing time on the Collin County
conviction, according to the district attorney’s office.
